All the risers will be on the same level. For example, if you set the first riser at 200mm, then you can’t set the next riser at 205mm. The levels will be all the same to prevent the hazard of tripping. 

  • Regulations For Maximum & Minimum Going of Stairs

The maximum rise for the staircase should be 170mm and the going should be 250mm. 

  • Regulations For Staircase Pitch

The maximum pitch of the commercial staircase should be 38° maximum. For domestic/private stairs it’ll be 42° maximum.  

  • Staircase Length & Width Regulation

For commercial usage, the length of the staircase must be limited to 16 risers maximum. And for the width,  it should be 1800mm maximum and there isn’t any minimum limit. But, the building control stipulated that no commercial staircase should be narrower than 860mm overall. 

But, if your staircase is more than 1000mm, then there must be a handrail on both sides. And if it’s 1800mm, then there should be handrails and spindles to separate the staircase. 

 

UK Regulations For Handrails & Balustrades 

 

Staircases must have handrails at one side at least if they are wider than 1000mm/1 meter. If it’s wider, then a handrail is a must on both sides. In all commercial buildings, the height of handrails should be between 900mm to 1000mm. It’s measured from the top of the handrail to the pitch line.

  1. There must be a landing at the top and bottom of every flight of stairs. 
  2. The landing distance at the anterior of the top and bottom step must be wider than the width of the staircase. 
  3. There shouldn’t be any door that will swing closer than 400mm in front of any step.

The Building Control requires for most of the staircases, the center of the winder tread depth must be equal to or larger than the depth of normal straight stairs. If the staircase is larger than 1000mm, then you should call for professional help.

How to Measure Staircase? 

 

When developing an idea or design for a staircase, the first thing you should consider is the size of the staircase. You can calculate the rise for determining the entire size of the staircase. Then, with the building regulations, you can determine the number of risers and the gap between those. 

For a domestic staircase, it’ll be 190mm to 220mm and for commercial purposes, it’ll be 150mm to 170mm. The gap between the risers should be 2000mm on average. Now, you can work on ‘going’. It’s a measurement from in front of one riser to the next. For the size, the going should be 220mm for domestic(private) buildings and 250mm for commercial buildings. 

Then, you can go for ‘treads’. Generally, treads are less than the total number of risers. And the size of treads is equal to or larger than the normal size of risers and going. For the pitch of the staircase, the angle shouldn’t exceed 42° for private property and 38° for commercial buildings.

Now, come for the width and length of the staircase. For mini, mum both kinds of buildings should have a minimum of 860mm width stairs, not narrower than it. For private properties, there aren’t any restrictions for length, but if the risers cross 36 numbers, then there should be a 30° change of direction. Spiral staircases are limited to 22 risers. 

For commercial buildings, if the length of the staircase crosses 1000, then there must be a handrail. And the total length shouldn’t cross 1800mm and if it’s 1800mm, there must be an extra handrail, spindle and newel to divide the staircase.
